Kev sib xyaw yog ib qho tseem ceeb tshaj plaws thiab cov kauj ruam nyuaj hauv kev ua cov roj hmab.Nws kuj yog ib qho ntawm cov txheej txheem feem ntau ua rau muaj kev hloov pauv zoo.Qhov zoo ntawm cov roj hmab compound ncaj qha cuam tshuam rau qhov zoo ntawm cov khoom.Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tau ua ib txoj hauj lwm zoo ntawm cov roj hmab sib tov.
Raws li cov khoom siv roj hmab, yuav ua li cas thiaj ua tau zoo ntawm kev sib xyaw roj hmab?Kuv xav tias ntxiv rau kev ua kom paub meej txog qhov tsim nyog ntawm txhua hom roj hmab, xws li cov yam ntxwv sib xyaw thiab kev sib xyaw ua ke, nws yog ib qho tsim nyog yuav tsum ua haujlwm hnyav, xav hnyav, thiab sib xyaw roj hmab nrog lub siab.Tsuas yog nyob rau hauv no txoj kev yog ib tug ntau tsim nyog roj hmab smelter.
Txhawm rau kom ntseeg tau qhov zoo ntawm cov roj hmab sib xyaw thaum lub sijhawm sib xyaw, cov ntsiab lus hauv qab no yuav tsum tau ua:
1. Txhua yam khoom xyaw nrog me me tab sis cov txiaj ntsig zoo yuav tsum tau muab sib xyaw ua ke thiab sib xyaw ua ke, txwv tsis pub nws yuav ua rau scorch ntawm cov roj hmab los yog cov vulcanization undercooked.
2. Kev sib tov yuav tsum tau ua raws li nruj raws li cov txheej txheem kev sib xyaw thiab kev noj zaub mov.
3. Lub sij hawm sib tov yuav tsum tau tswj kom nruj, thiab lub sij hawm yuav tsum tsis txhob ntev los yog luv heev.Tsuas yog nyob rau hauv txoj kev no tuaj yeem lav qhov plasticity ntawm cov roj hmab sib xyaw.
4. Tsis txhob muab cov pa roj carbon ntau ntau thiab cov fillers pov tseg, tab sis siv lawv.Thiab ntxuav lub tais.
Tau kawg, muaj ntau yam uas cuam tshuam rau qhov zoo ntawm cov roj hmab compound.Txawm li cas los xij, qhov tshwj xeeb tshwm sim yog qhov tsis sib xws ntawm cov neeg sawv cev sib xyaw, Frost tsuag, scorch, thiab lwm yam, uas tuaj yeem pom pom.
Kev tsis sib haum xeeb ntawm tus neeg sawv cev sib xyaw Ntxiv Ntxiv rau cov khoom sib xyaw ua ke ntawm cov khoom siv roj hmab, txiav cov zaj duab xis nrog rab riam, thiab yuav muaj cov khoom sib xyaw ua ke ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv roj hmab.Lub compound yog tov tusyees, thiab seem yog du.Yog tias qhov tsis sib xws ntawm qhov sib xyaw ua ke tsis tuaj yeem daws tau tom qab rov ua dua tshiab, cov roj hmab cov menyuam yuav raug muab pov tseg.Yog li ntawd, cov roj hmab sib tov yuav tsum nruj me ntsis raws li cov txheej txheem kev cai thaum lub sij hawm ua hauj lwm, thiab los ntawm lub sij hawm mus rau lub sij hawm, coj cov zaj duab xis los ntawm ob qho tib si hnub thiab nruab nrab ntawm cov menyuam los saib seb cov compounding tus neeg sawv cev yog sib npaug zos.
Frosting, yog tias nws tsis yog qhov teeb meem ntawm cov qauv tsim, ces nws yog tshwm sim los ntawm qhov kev txiav txim tsis raug ntawm kev noj tshuaj thaum lub sij hawm sib tov, los yog qhov sib tov tsis sib xws thiab cov agglomeration ntawm tus neeg sawv cev compounding.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj cov txheej txheem sib tov kom tsis txhob muaj qhov tshwm sim tshwm sim.
Scorch yog ib qho teeb meem tseem ceeb tshaj plaws hauv kev sib xyaw ua ke.Tom qab cov khoom siv roj hmab yog scorched, qhov saum npoo los yog sab hauv muaj cov khoom siv roj hmab uas muaj elastic.Yog tias scorch me ntsis, nws tuaj yeem daws tau los ntawm txoj kev nyias dhau.Yog tias scorch hnyav, cov khoom siv roj hmab yuav raug muab pov tseg.Los ntawm kev xav ntawm cov txheej txheem txheej txheem, scorch ntawm cov roj hmab compound feem ntau cuam tshuam los ntawm qhov kub thiab txias.Yog tias qhov kub ntawm cov roj hmab sib xyaw yog siab dhau, cov roj hmab nyoos, tus neeg sawv cev vulcanizing thiab accelerator yuav hnov mob thaum lub sij hawm sib tov, uas yog, scorch.Nyob rau hauv ib txwm muaj xwm txheej, yog tias cov roj hmab thaum lub sij hawm sib tov yog loj heev thiab qhov kub ntawm cov menyuam yog siab dhau lawm, qhov kub ntawm cov roj hmab yuav nce, uas ua rau scorch.Tau kawg, yog tias qhov kev noj zaub mov tsis tsim nyog, qhov sib ntxiv ntawm vulcanizing tus neeg sawv cev thiab cov accelerator yuav yooj yim ua rau scorch.
Qhov hloov pauv ntawm hardness kuj yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov roj hmab compound.Cov sib xyaw ntawm tib lub hardness feem ntau sib xyaw nrog cov hardness sib txawv, thiab qee qhov sib txawv.Qhov no feem ntau yog vim qhov tsis sib xws ntawm cov roj hmab sib xyaw thiab qhov tsis zoo ntawm cov neeg sawv cev sib xyaw.Nyob rau tib lub sijhawm, ntxiv tsawg dua lossis ntau dua cov pa roj carbon dub kuj yuav ua rau muaj kev hloov pauv hauv cov tawv tawv ntawm cov roj hmab sib xyaw.Ntawm qhov tod tes, qhov tsis raug qhov hnyav ntawm tus neeg sawv cev compounding kuj yuav ua rau muaj kev hloov pauv hauv qhov nyuaj ntawm cov roj hmab sib xyaw.Xws li kev sib ntxiv ntawm vulcanizing tus neeg sawv cev thiab accelerator carbon dub, lub hardness ntawm cov roj hmab compound yuav nce.Cov softener thiab raw roj hmab yog hnyav dua, thiab cov pa roj carbon dub yog tsawg, thiab cov hardness ntawm cov roj hmab compound ua me.Yog hais tias lub sij hawm sib tov ntev dhau lawm, lub hardness ntawm cov roj hmab compound yuav txo.Yog hais tias lub sij hawm sib tov yog luv luv, lub compound yuav harden.Yog li ntawd, lub sij hawm sib tov yuav tsum tsis txhob ntev los yog luv heev.Yog tias qhov sib tov ntev dhau lawm, ntxiv rau qhov txo qis hauv hardness ntawm cov roj hmab, lub zog tensile ntawm cov roj hmab yuav txo qis, qhov elongation ntawm kev tawg yuav nce, thiab kev laus kuj yuav txo.Nyob rau tib lub sijhawm, nws kuj ua rau cov neeg ua haujlwm siv zog thiab siv zog.
Yog li ntawd, qhov sib tov tsuas yog yuav tsum muaj peev xwm ua kom tag nrho cov neeg ua haujlwm sib xyaw ua ke hauv cov roj hmab sib xyaw, thiab kom ntseeg tau tias cov khoom siv lub cev thiab cov khoom siv thiab cov kev xav tau ntawm calendering, extrusion thiab lwm yam kev ua haujlwm.
Raws li cov khoom siv roj hmab tsim nyog, tsis yog tsuas yog muaj lub luag haujlwm muaj zog, tab sis kuj yuav tsum paub txog ntau yam roj hmab thiab cov khoom siv raw.Ntawd yog, tsis yog tsuas yog nkag siab txog lawv cov haujlwm thiab cov khoom, tab sis kuj tseem tuaj yeem ua kom raug lawv lub npe yam tsis muaj cov ntawv sau, tshwj xeeb tshaj yog rau cov tebchaw uas zoo sib xws.Piv txwv li, magnesium oxide, nitric oxide thiab calcium hydroxide, siab hnav-resistant carbon dub, ceev-extrusion carbon dub thiab semi-reinforced carbon dub, raws li zoo raws li domestic nitrile-18, nitrile-26, nitrile-40 thiab hais txog.
